I know they are sensitive when it comes to dropping and that dropping one will most likely render it useless, but what, other than dropping one causes it to fail?

Can one that has sat for a couple of months "ruin" it?

I ask because when ever i first got my sr swap running and hooked up to consult, i had a code 34.

Replaced the sensor and didn't see the code 34 again.

Removed engine to do some shit and it sat for 2 months.

Put engine back in and I'm now getting a code 34 again.

Ive already bought a new sub harness and getting a new knock sensor as well. Should both be here this week

Im only asking because I'm curious.
